Hi there, from an ex-Maineiac. There's a local recycling place that has one A500 PSU brick for $5. I'll go retreive it and hold it for you if you do that + the shipping. Just use the USPS calculator from Oakland CA 94612
I'm curious if you've been to Searsport computers in Belfast recently? Thats where I got my A500 and GVP530 HD and some software back in the 90's.
